Step ladder apparatus
First Claim
1. A step ladder apparatus for use in association with a trailer, the step ladder configured for retention within a stake pocket, comprising:
- a frame assembly having a first end and a second end, the frame assembly comprising an elongated member having a front wall and opposing sides;
a plurality of step assemblies spaced apart from each other and positioned along the frame assembly between the first and second ends thereof;
an attachment assembly comprising;
a frame flange coupled to the frame assembly and extending outwardly proximate the first end and in a direction away from one of the opposing sides of the frame assembly; and
a wedge member separate from the frame assembly and the frame flange, the wedge member comprising a base and a wedge flange member extending therefrom, in operable engagement, the base spacing the wedge flange apart from the frame assembly, the base of the wedge member and the frame assembly together substantially corresponding to the width of the stake pocket;
whereupon the frame assembly is positioned within the stake pocket so that the frame flange overhangs one end of the stake pocket and whereupon the base of the wedge member is inserted into the stake pocket opposite the frame flange so that the base spaces the wedge flange apart from the frame assembly and so that the wedge flange overhangs the stake pocket on a side opposite the frame flange, the flanges cooperate to substantially preclude sideways and downward movement of the frame assembly, and, in turn, removal of the frame assembly in a downward direction from the stake pocket.

Abstract
A step ladder apparatus for retention within a stake pocket comprising a frame assembly a plurality of step assemblies and an attachment assembly. The attachment assembly includes a frame flange and a wedge member. The frame assembly is positioned within the stake pocket so that the frame flange overhangs one end of the stake pocket. The base of the wedge member is inserted into the stake pocket opposite the frame flange so that the wedge flange overhangs the stake pocket on a side opposite the frame flange. As a result, the flanges cooperate to substantially preclude downward movement of the frame assembly, and, in turn, removal of the frame assembly in a downward direction from the stake pocket.
